A system for inserting a cannulated tissue anchor during endoscopic surgical procedures. The system incorporates an elongated generally cylindrical tissue anchor having a plurality of barbs outwardly extending from its body and a transverse head situated at its proximal end. The head is elongated along a major axis which is misaligned relative to the rows of barbs on the body of the tissue anchor in order to enhance retention of the anchor within selected tissue. The anchor may be inserted during an endoscopic surgical procedure by a single-handed operation utilizing an instrument having a longitudinally slidable needle for guiding the anchor into place and a longitudinally slidable push rod for pushing the anchor along the needle. The system incorporates a package/loading device to facilitate the assembly of a cannulated tissue anchor with the inserter, the package/loading device being provided with a means for guiding the inserter needle through the axial bore of the tissue anchor.
